The efficacy of dietary curcumin on growth performance, lipid peroxidation and hepatic transcription factors in rainbow troutOncorhynchus Mykiss(Walbaum) reared under different stocking densities

Curcumin, derived from Curcuma longa, exerts antioxidant, antibacterial, anticancer and immunomodulatory properties. This study was conducted to determine the effect of dietary water-soluble curcumin (0, 200 or 400 mg kg−1) on growth performance and antioxidant status in rainbow trout (Oncorhynchus mykiss, Walbaum) rearing under normal (20 kg m−3) or high (100 kg m−3) stocking density conditions. A significant increase in body weight (FBW), feed intake (FI) and weight gain (BWG) was observed in fish fed with curcumin-supplemented diet at 200 mg kg−1 of diet levels of high stocking density conditions (P
